Yemen's exiled president met Secretary of State John Kerry on Thursday, his first meeting with a top-level U.S. official since fleeing his country amid an advance by Iran-linked rebels, NBC News reported. "Ah, there's some work to do," Kerry told Abed Rabbo Mansour Hadi in the Saudi capital of Riyadh. "Let's do the work." Hadi is Yemen's internationally-recognized president and has been backed by the U.S. as a key ally against al Qaeda in the Arabian Peninsula. He fled Yemen for Saudi Arabia in late March after Shiite Houthi rebels, backed by forces loyal to the president's predecessor, attempted to seize power. In addition to his meeting with Hadi, Kerry was expected to hold discussions in Riyadh with the Saudi government about a "pause" in the conflict so humanitarian assistance could be delivered.
